I know. I'm not saying it wasnt planned, it's just that it was officially introduced 500 chapters too late for my taste. There is just too many haki user for it to be a secrets.
The detailed explanation is out of nowhere. Calling it willpower alone would have been fine, we didn't need different type with different powerlevel or w/e.And also it is in the 1st chapter, mantra was on sky island, Shanks used it again when he came aboard Whitebeard's ship after Enies lobby. Haki has been a long time coming, and isn't "out of no where."
If it remains like it is right now...it's not so bad, but that kind of power always get out of hand in shonen.
